我有一个 Django 项目,我正在处理我想要流式传输一些 mp3 文件的地方。
我有同样的问题: Streaming mp3 files with django, read from a page with <audio>
让我解释一下:我想用 Django流式传输一个 ogg<audio>
,并在我的 html 页面中使用一个标签
我有一个类似的网址,我的歌曲的 ID 在domain.tld/song/show/X/
哪里。X
我可以使用 VLC 进行流式传输(直接使用文件路径),我可以在测试期间进行流式传输(我编写接收到的内容并使用 VLC 读取它)。
但是当我打开浏览器并加载我拥有的主页domain.tld
并<\audio\>
使用 url 进行应答时domain.tld/song/show/1/
,我得到了一个大的破管道,就好像我的客户端关闭了连接一样。
我在其他帖子上读到,当他们将服务器投入生产时,一些问题得到了解决。所以我将我的应用程序推送到服务器上,使用 apache,以及django.wgsi
djangoproject.com 上的类似内容。
我在 Debian 7 上使用 Django 版本 1.5 运行 python 2.7.3。那里有我的代码:
歌曲/views.py
def playAudioFile(request, pk):
f = get_stream_song(pk)# return a pipe from pipes.Template
l = f.read() # the file is an ogg get by pydub.com
f.close()
size_read = 550000
sr = size_read
while sr == size_read:
print "rep"
r = l[:size_read]
l=l[size_read:]
sr = len(r)
yield r
time.sleep(0.1)
#url : ~/song/show/X/
#@login_required
def show_song(request, pk):
return StreamingHttpResponse(playAudioFile(request, pk), mimetype='audio/ogg',)
在我的 HTML 中,我只有:
<audio controls height="100" width="100" preload="auto">
<source src="/.../song/show/1/" type="audio/ogg">
<embed height="50" width="100" src="/.../song/show/1/">
</audio>
错误看起来像:
Traceback (most recent call last):
File "/usr/lib/python2.7/wsgiref/handlers.py", line 86, in run

每次尝试流式传输时,我都会得到两次。

我按照 rahan 的建议做了:查看 Firebug 和 Firefox 调试器:
